The Twilight actress, who stars in new coming-of-age movie On The Road, confessed to V magazine: "It's a pretty f***ing odd thing to want to pretend to be another person and then have a lot of other people who watch you do that."

The 22-year-old explained: "You have this experience of reading something, and if you don't bring it to life, you're basically deleting it.

"Every day of shooting you're depriving the world of having that. The responsibility is amazing."
